The one thing I don't understand is why IS feels the need to make every character able to support every character of the opposite sex. Sure, it allows for more customization of pairings for each playthrough, but in a lot of cases, these characters have nothing in common or have no reason whatsoever to interact, and because of that, a lot of these characters' defining traits get milked way more than they should. Take Felicia, for example. Being a clumsy maid is cute and all, but it starts to get annoying when it's the main topic of almost all (over 20!) of her conversations. I can see why Kamui would be able to support with everyone, but not so much for the rest of the cast.
IS really should just have limited supports between opposite sexes to around four to six or something, only having characters with similarties or history together being able to support with one another (Kagerou only being able to support with Suzukaze, Kamui, Saizou and Ryouma for example, pretty much no one is planning to pair her up with Tsukuyomi or something from what I've seen so far). I'd rather have a smaller amount of well-written and interesting conversations than a crapload of rushed conversations that all revolve around the exact same topic.
Also, less incest in the localization would be appreciated, heheh. Making Mikoto and Shinmei childhood friends / very distantly related instead of being siblings would be a good start.
